Today I have decided to blog about Atm’s as everyone knows what a vital role they play in today’s world. People need not go into a bank to handle cash anymore as you can now do it on almost every street corner. With this in mind it is very easy to forget that an ATM is a very complex machine with a huge system at the head of its operations

ATMs are like a big computer but they are not run with the same type of system. An ATMs only function is to be an ATM. The debit card readers and cash dispensers in an ATM are not unlike a printer on your PC. Once you insert your card to be read information is sent to be interpreted into data. Once your transaction has been authorized a code is sent to dispense the right amount of cash. The ATM is like the nerve-center of the transaction and the peripherals as hands.

Alot of infrastructure is in place to keep you safe while using an ATM.Almost all ATMs are connected using normal computer network standards. all communications are kept safe with an encryption which keeps your transactions from anyone. Also every ATM is connected to a bank. This allows the ATM to authenticate your card and check that the transaction is going through to the right account etc. Even if you use an ATM that is from another bank the the banks database can decipher what account tou are using and where the money needs to come from and go to.

It is a very clever and useful system that without it in the world today life would be much slower and banking would be even more time consuming. I hope you enjoyed this blog as i found the topic very interesting.
